Beyonce showed off her hot swimsuit body while vacationing in California this week.

Beyonce has maintained her 65-pound post-baby weight loss for more than 3 years with a vegan diet, Examiner reported.

Beyonce, who lost 65 pounds six months after giving birth to daughter Blue Ivy in 2012, said her vegan diet enables her to easily maintain her weight loss and gives her lots of energy.

Beyonce praised her longtime fitness trainer, Marco Borges, author of The 22-Day Revolution. Beyonce said her vegan diet not only caused her dramatic weight loss, but gave her glowing skin.

“I felt like my skin was really firm, a lot tighter than when I deprived myself of food and got the weight off fast,” said Beyoncé. “And the weight stayed off.”

Beyonce, who weighed 195 pounds while pregnant, lost 65 pounds in 6 months with a vegan diet.

The 5-foot-7 Beyonce, who once weighed 195 pounds, lost 65 pounds using Marcos’ vegan diet plan, and said it can do the same for you.

Beyonce has since maintained her weight loss and recently made jaws drop after flaunting her unbelievable body in a nude Givenchy gown at the 2015 Met Gala.

Marco Borges, who has trained Beyonce since 2007, said her mostly vegan diet is responsible for her smoking-hot body. Similarly, Jennifer Lopez has credited Marco’s 22-day vegan diet for her 10-pound weight loss and age-defying beauty.

According to Borges, CEO of 22 Day Nutrition protein bars, following a vegan diet will promote effortless weight loss and dramatically improve your health.

“With most diets, you see weight loss and then as soon as the program ends the weight slowly starts to add back up again,” said Borges. “With ‘The 22-Day Revolution, you’ll experience weight loss, improved sleep, clear skin, increased energy, improved sex drive and more.”
